What Sangyo Sosei Advisory does
Sangyo Sosei Advisory (株式会社産業創成アドバイザリー) is an independent, founder-owned boutique M&A and financial advisory firm headquartered in Tokyo's Ginza district, established in December 2009 by Sato Fumiaki, Abe Atsushi, and Gary Chan — three former senior professionals from Merrill Lynch, Unitas Capital, and UBS. The firm specializes exclusively in Japan's TMT (Technology, Media, Telecommunications) and renewable energy sectors, providing M&A advisory (buy-side and sell-side), capital raising, fairness opinions, and strategic consulting to large enterprises, private equity funds, and government-linked investment bodies. Its track record includes landmark transactions such as the formation of Japan Display, the eAccess/eMobile integration (later sold to SoftBank), the CDPQ JPY 70 billion investment in Shizen Energy, and the DigitalBridge tender offer for JTOWER, the latter shortlisted for Digital Infrastructure M&A Deal of the Year 2025.
The firm operates a pure relationship-driven go-to-market with all client engagements sourced and managed directly by senior partners and managing directors, relying on personal networks, referrals, and thought leadership in Japanese business media (Nikkei, Reuters, Bloomberg) rather than outbound sales or marketing. Revenue is generated through project-based professional services fees tied to transaction completion, with no subscription or recurring component. SSA also manages the SSC01 investment fund under Japan's eligible institutional investor special business operator framework (適格機関投資家特例業務届出者), providing a regulated channel for co-investment and capital deployment alongside pure advisory mandates.
The senior team has been progressively expanded with the addition of Semmoto Yukio (former KDDI, e-Access, Renova leader) as Senior Partner in May 2024, the promotion of Nakajima Hideyuki to Partner in December 2019, and new member additions in 2021 and 2024-2025. The firm is privately held with no external institutional ownership, employs 1-10 people, and celebrated its 15th anniversary in December 2024. A key recent event was the passing of co-founder Abe Atsushi on January 3, 2025, which triggered a leadership transition at the founding-partner level.

Sangyo Sosei Advisory competitors and assessment
Company assessmentBroad incumbents
- Rothschild & Co: Global independent M&A advisory with strong mid- and large-cap TMT and energy franchises globally. Rothschild competes for Japanese cross-border mandates of the same nature as SSA's, offering broader geographic reach as a larger incumbent.
- Lazard: Global M&A and financial advisory firm with a deep TMT and energy practice in Japan and Asia. Lazard competes with SSA for high-end Japanese corporate and sponsor mandates but operates as a broad incumbent across many sectors rather than a sector boutique.
- Houlihan Lokey: Global independent advisory firm (which absorbed Japan's former GCA Corporation). Houlihan Lokey/GCA competes with SSA on Japanese mid- and large-cap M&A mandates across TMT and infrastructure, with a broader product suite including fairness opinions and restructuring.
- Greenhill & Co (Mizuho): Independent M&A advisor acquired by Mizuho in 2023, providing Mizuho with sector-focused M&A capability similar to SSA's boutique model. Greenhill/Mizuho now competes on Japanese TMT and infrastructure mandates where SSA has historically been engaged by sponsors.
- Nomura Securities: Japan's largest domestic investment bank with a TMT investment-banking franchise and a dedicated renewable-energy/infrastructure team (including Greentech). Nomura competes with SSA on Japanese corporate sell-side mandates and capital-raisings, especially those requiring balance-sheet capability.
- SMBC Nikko Securities: Japanese bulge-bracket with active TMT M&A coverage (where current SSA MD Tsukidate previously led the Second Investment Banking Division). Competes with SSA on Japanese TMT sell-side and capital-raise mandates, especially where financing capability matters.
- Daiwa Securities: Japanese bulge-bracket with global investment banking and equity capital markets coverage. Daiwa competes with SSA on Japanese TMT and infrastructure M&A mandates and equity offerings, offering scale and capital-markets execution unavailable to SSA.
- Mitsubishi UFJ Morgan Stanley Securities: Japanese bulge-bracket with one of the largest TMT M&A practices in Tokyo and historical employer of multiple SSA senior bankers. Competes with SSA on large Japanese corporate TMT sell-side, IPO and ECM mandates where balance-sheet and underwriting scale are valued.
Direct peers
- Arma Partners: Independent global advisor focused exclusively on technology, media and telecommunications M&A. Arma Partners pursues the same specialist-TMT value proposition as SSA and frequently appears on Asia-Pacific TMT sell-side and buy-side mandates alongside or against SSA.
- DC Advisory: Global TMT, digital infrastructure and energy M&A boutique with a longstanding Tokyo office. DC Advisory competes head-to-head with SSA on Japan-focused TMT, data-center and renewable-energy mandates from sponsors and corporates, with a similar boutique delivery model and sector specialist profile.
